How to Add Protein to Smoothies

Everything you need to know about high-protein smoothies.

If you’ve ever wondered how to add protein to smoothies, you’re in the right place. Whether you're searching for a protein smoothie recipe or a new smoothie recipe to try, we've got it all. In this guide, we’ll cover everything from different plant-based protein sources and easy smoothie ideas to simple flavor additions like vanilla extract.

Are smoothies with protein good for you?

Protein smoothies are nutritious and have a variety of benefits like supporting bone health, balancing blood sugars and helping with muscle growth, to name a few. Protein smoothies are usually made with one fruit and/or vegetable, a liquid, as well as a protein source like greek yogurt, cottage cheese, silken tofu, or protein powder. Plus, smoothies are a convenient way to boost your intake of fruits, vegetables, and other fiber-rich foods. To keep smoothies healthy, try to use whole fruits, such as a ripe banana, to add sweetness instead of honey or maple syrup or added sugar.

Benefits of Adding Protein to Your Smoothie

Protein is the MVP when it comes to making smoothies more than just a tasty treat. Here's why it’s worth the hype:

• Keeps you fuller for longer - Protein slows digestion, helping you avoid those mid-morning snack attacks.
• Supports muscle recovery - Whether you’re hitting the gym or just tackling a busy day, protein helps repair and build muscles.
• Boosts metabolism - Protein takes more energy to digest than carbs or fat, giving your metabolism a little extra push.
• Balances energy levels - Pairing protein with fruits and veggies helps regulate blood sugar spikes for steady energy throughout the day.

What can you add into a smoothie for protein?

Protein powder is one of the easiest ways to add protein to a smoothie. Protein powders are dietary supplements that can help you meet your protein goals. Protein powders come in a variety of flavors and can be added to smoothies, shakes, and other foods.  You can even try powdered peanut butter for a nutty twist!

There are a lot of different types of protein powders at your local grocery store. Some protein powders are better for building muscle, while others help with weight loss or muscle repair after a workout. Make sure to choose a protein powder without any added sugars. That way, you can add sweetness naturally (think: ripe banana) to your smoothie. 

How to Balance Protein, Carbs, and Fats in a Smoothie

A high-protein smoothie is great, but it’s even better when it’s balanced with the right mix of macronutrients. Here's how to nail the combo:

• Protein - Start with a solid protein source, like Greek yogurt or a scoop of protein powder.
• Carbs - Add a natural source of carbohydrates, like a ripe banana or frozen mango, for energy and sweetness.
• Fats - Include healthy fats from nut butter, chia seeds, or avocado to help your body absorb nutrients and keep you satisfied.

Pro tip: Stick to the 40-30-30 rule (40% carbs, 30% protein, 30% fat) for a smoothie that’s nutritious and balanced.

How can you get protein in your smoothie without protein powder?

Protein powder is a convenient way to add protein to a smoothie, but it’s not everyone’s jam. Protein powder is a form of processed food, and using real ingredients is always the best choice for a homemade smoothie.

Check out nine ways to add protein to a smoothie with whole foods:

• Plain yogurt. Unsweetened plain yogurt adds protein to a smoothie and a rich, creamy texture.
• Kefir. This is a fermented milk beverage that’s like yogurt. Kefir is a combination of bacteria and yeast fermentation and contains a higher amount of beneficial probiotics with a slightly more bitter taste. Kefir can be blended into any smoothie but tends to pair the best with berries.
• Hemp seeds. Hemp seeds (or hemp hearts) have a mild and nutty flavor and are a good source of plant protein and omega-3 fatty acids.
• Chia seeds. Just a tablespoon of chia seeds will add more protein, omega-3 fatty acids, and fiber to a smoothie. Plus, chia seeds are a natural thickening agent and make for a rich, luscious consistency. Feel free to also try sesame seeds for a unique twist.
• Flax seeds. Similar to chia seeds, flax seeds offer a bit of protein, omega-3 fatty acids, and fiber to a smoothie. Plus, a nice nutty flavor and creamy texture.
• Nut butter. Nut butters (such as peanut butter, almond butter, cashew butter, and walnut butter) have a thick creamy texture and protein. Choose a natural nut butter that requires stirring and avoid “no stir” butters with added rapeseed oil or palm oil for easy spreading. Hydrogenated oils can increase bad cholesterol levels.
• Cow’s milk. If you can tolerate dairy, whole milk is a tasty and easy way to up your protein intake.
• Plant milk. Can’t handle dairy? No problem. Pea milk (8g of protein per cup), soy milk (6.5 grams of protein per cup), cashew milk (4.5 g of protein per cup) and hemp milk (3g of protein per cup) are great alternatives to help round out a complete protein profile in your smoothie.
• Silken tofu. Tofu is a source of plant-based protein and soft tofu blends up smoothly. You can even use any leftover tofu from your smoothie in a veggie stir-fry for dinner.

There are *so many* ways to mix and match protein sources in a smoothie. When it comes to customizing smoothies, you can also switch up the fruits, vegetables, liquids, bases, and add-ins.
